I had swelling in 2 nd last gum and loose teeth 8 months ago, I consulted Dr he gave me antibiotic and zingisol for massage. which helped me but it happened quite often approx every month, I took antibiotics regularly. Recently since a month a pus ball formed pus started draining out of it, even antibiotics were not effective. I consulted dentist and he has started root canel, I had three sittings with him but the pus is reduced but there is red mass near the wound of pus ball. I used to chew tobacco since 3 yrs which I have quitter since fifteen days, can u suggest is the treatment of the Dr fine
